CCI Steel Construction & Welding Inspection 3

Question 1

An inspector is verifying the size of a fillet weld. Which tool is specifically designed for this measurement?

Accepted Answer

Weld gauge (fillet weld gauge)

Answer

A fillet weld gauge is specifically designed to measure the leg size and throat of fillet welds, making it the correct tool for verifying fillet weld dimensions.

Question 2

Which of the following discontinuities in a weld is considered a linear planar defect most critical to structural performance?

Accepted Answer

Lack of fusion

Answer

Lack of fusion is a planar discontinuity where weld metal fails to bond with adjacent base metal or a previous weld pass, creating a sharp notch that severely degrades structural performance.

Question 3

What is the effective throat of a 3/8-inch fillet weld made using the standard 45° fillet geometry?

Accepted Answer

0.265 inch

Answer

The effective throat of a standard 45° fillet weld equals 0.707 times the leg size; 0.707 × 0.375 ≈ 0.265 inch, which is used in strength calculations.

Question 4

According to AISC 360, which connection type requires that the bolt holes be aligned and the bolts installed in a specific sequence to ensure proper load distribution in slip-critical connections?

Accepted Answer

Slip-critical connection

Answer

Slip-critical connections rely on friction between faying surfaces to transfer loads; proper bolt installation sequence and pretension are essential to develop the required clamping force.

Question 5

When inspecting structural steel mill certifications (MTRs), which property confirms that the steel will absorb sufficient energy before fracturing in cold temperatures?

Accepted Answer

Charpy V-notch impact value

Answer

The Charpy V-notch (CVN) impact test measures the energy absorbed by a steel specimen during fracture at a specified temperature, indicating the material's notch toughness and resistance to brittle fracture.
